Be it known that I, ARTHUR W. FREEsE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement inr Back finders or Skeiners, of which the following is a specification.

The principal object of the present invention is to provide a simple, comparatively inexpensive and efficient machine which will back-wind knit goods from single, doublelock or circular machines and will also unravel shaker rib and silks of any kind and which does not require skilled labor for its operation.

The invention will be claimed at the end hereof but, generally stated, it comprises the combination in a back Winder of a pedestal having yarn guides, a shaft mounted for rotation and endwise reciprocation on the pedestal and provided with reels, an endless groove provided on the shaft and of the form of an intersecting right and left hand spiral, a shoe pivotally mounted onk the pedestal and adapted to traverse said groove to cause endwise reciprocation of the shaft when it is rotated, and limit stop positioning mechanism for the shoe.

In the drawings forming part hereof?- Figure l is a front view of the machine with the yarn guides and certain other parts omitted for the sake of clearness.

Fig. 2 is an end view of the machine.

Fig. 3 is a top or plan view.

Fig. a is a view drawn to an enlarged scale illustrating the reel mounting.

F ig. 5 is a top or plan detail view.

Fig. 6 is an elevational detail View, and

Fig. 7 isa sectional view on the line 7-7 of Fig. 5.

In the drawings 1 is a pedestal provided with a bracket 2 carrying yarn guides 3. i is a shaft mounted for rotation and endwise reciprocation on the pedestal. The shaft is driven from an electric motor 5 by means of sprocket gearing G, which, while turning the shaft, affords it endwise mo` tion suiiicient for the purposes of the niachine. 7 are reels mornted on the shaft 4: between collars 8, and they are driven from the shaft by spring pressed plungers 9, Fig. 4, the pressure of which can be adjustedV by set screws 10, thus the reels may be run at different peripheral speeds or at the same peripheral speed. l1 is an endless groove provided on the shaft 4 and of the form of intersecting right and left hand spirals.

12 is a shoe pivotally mounted on the pedestal and adapted to traverse the groove 11 to cause endwise reciprocation of the shaft 4 and of the reels r7 as the shaft is rotated. 13 is a spring arm extending from the shoe and co-operating with a cam 14e having two stops 15 with a high part 16 between them for transferring the arm 13 from one stop to the other with a quick motion in order to insure proper travel of the shoe in the right and left hand spirals of the groove 11. lThe face of the shoe is concave and elongated, Figs. 5 and 7, and this oblong shoe works between the confronting walls of the spiral groove and is pivotally" supported. In order to guide it at the crossings of the groove 11 so that it will run from end to end thereof, the shoe is provided with a spring arm 13 which bears down onto the cam 14. The cam 14 has two upright walls 15 with upwardly sloping walls that constitute a high part 16 between them. At the end of the groove 11 the shoe iturns and the spring arm slides down one or the other of the walls constituting the high part 16 and comes to rest against one of the stops, thus automatically positioning the shoe so that it will not run out of the groove 11 at the crossingsathereof but will turn properly at the ends of the groove.

In use the groove 11 meshing with the shoe 12 shifts the reels back and forth in endwise direction with respect to the yarn guides 3, and the reels through the operation of the friction drives 9 maybe run at the same or at different peripheral speeds winding the yarn which is indicated at a in Fg. 2, and also nagging it.

It will be obvious to those skilled in the art to which the invention relates that modifications may be made in details of construction and arrangement without departing from the spirit of the invention which is not limited as to those matters or otherwise than as the prior art and the appended claims may require.

I claim: 1. A back Winder or skeiner comprising in combination a pedestal having yarn guides, a shaft mounted for rotation and endwise reciprocation on the pedestal and provided with reels, an endless groove provided on the shaft and of the form of intersecting right and left hand spirals, a shoe pivotspirals, a pivotal shoe, a springy arm for thev shoe, and a cam coeoperating With the arm, f

substantially as described.. Y

3. A back Winder or skelner comprising the combination of sidewise movable reels,k

thread or yarn guides, mechanism for reciprocating the. reels sidewise which includes a relatively fixed pivotal shoe and a sidew'ise movable rotatingelement having an endless groove of the form of intersecting rightand left hand spirals and a spring arm and cam for positioning the shoe, substantially as described. y Y
